Heat pump vs. gas furnace in Seal Beach, CA
Seal Beach sits right on the fence — how long you'll own the house decides this one. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $1,000 after a $2,000 federal tax credit. That premium is recovered through $72 of lower running costs every year, landing the payback clock at roughly 13.9 years. Whether that's worth it in Seal Beach depends on how many years you expect to own the place.
Why Seal Beach's climate drives this number
1514 heating degree days pile up here every year, so Seal Beach has a mild winter by US standards; the cooling side runs to 738 cooling degree days, where summers add a moderate cooling load. Sizing runs off the design temperature, not the average day: 36.5°F here (record low 35.2°F), which works out to a seasonal COP of 3.29 for the standard class of unit this climate calls for. A standard ducted system is enough here; Seal Beach's design temperature doesn't justify the cold-climate premium.

What it actually costs to run, year to year
A 2000-square-foot house here would pull roughly 1,165 heating kilowatt-hours annually on top of cooling, totalling about $589 a year on electricity. The gas furnace it replaces burns roughly 16 Mcf a year at 22.01 per Mcf here, for a running cost near $661 a year (electricity here runs 32.83¢/kWh). Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 152.9 years, for a 15-year net position $79 ahead.
The other scenario: no gas furnace to begin with
Gas isn't universal in Seal Beach — many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Seal Beach's answer improves. About $983 a year comes back this way, enough that the 5.6-year payback clears the $5,500 premium comfortably within the equipment's life.
Seal Beach against the rest of the country
Among 3206 cities, Seal Beach's winter puts it at rank 2687 for severity, while its size puts it at rank 1644 for population — 1 in both cases being the extreme. That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.

Where Seal Beach's figure comes from
Nothing above is a black box: the methodology guide shows the full arithmetic behind Seal Beach's 3.29 seasonal COP and payback figure. Not every home in Seal Beach has gas; the guide comparing a heat pump against electric baseboard covers that case separately.
